Abstract (en)

The operational efficiency of a filter (9), employed to remove aerosol particles from a gas flow (4), is determined. The particle concentration (c(1) is measured in the raw gas before (9), and immediately (c(2) after the filter. The particle separation A is given by the formula A = 1 - c(2/c(1. To warn of possible filter leaks or failure, the cleaned gas is sampled by a suction unit (11), which is drawn once over the entire filter outlet surface. An Independent claim is included for a commensurate sampling assembly.
